The guide also highlights common setup and run pitfalls that appear across the covered tools.
What Is Hydraulic Simulation Software?
Hydraulic simulation software computes water movement through networks and floodplains by solving for flows, water levels, pressures, and time-varying behaviors. It is used to test stormwater drainage performance, sewer surcharge and pumping operations, pressurized distribution hydraulics, and floodplain inundation extents. For example, InfoWorks ICM couples 1D sewer networks with 2D overland flooding in a single GIS-driven workflow. EPANET focuses on pressurized water distribution networks with steady-state and extended-period simulations that include pumps, valves, tanks, and time-varying demands.
Key Features to Look For
The right feature set depends on whether the study is pressurized networks, gravity sewers, or 1D-2D flood hydraulics with GIS-based model building.
Unified coupled 1D and 2D modeling for sewer and surface flooding
Unified 1D-2D coupling is the deciding feature when sewer capacity and surface inundation must be analyzed together in one model. InfoWorks ICM is built around unified 1D and 2D coupling for sewer capacity and surface inundation simulation. TUFLOW also delivers coupled 1D-2D modeling for realistic channel and floodplain hydraulics.
GIS-linked data import, editing, and scenario iteration
GIS-linked workflows reduce rework during iterative design and reruns because geometry and boundaries remain connected to model inputs. InfoWorks ICM provides GIS data import and editing that speeds model setup and updates. GMS adds an integrated GIS-to-mesh workflow that streamlines geometry preparation and study reruns.
Extended period simulation with time-varying demands and operational controls
Extended period simulation is critical when hydraulics change across a horizon due to demand patterns, pump schedules, or tank cycling. EPANET supports extended-period hydraulic simulations with time-varying demands plus pumps and tanks. CivilStorm targets steady and dynamic simulation with pump station operations and storage interactions for time-varying stormwater and sewer behavior.
Dynamic stormwater and sewer modeling with event-based hydrographs
Event-based outputs like hydrographs support design checks that depend on transient peaks and storage effects. CivilStorm generates water levels, flows, and hydrographs that can be compared across scenarios for event-based design. Flood Modeller supports scenario management for repeat flood runs with map-based hydraulic outputs.
SWMM-centric project workflow for structured drainage model review
A SWMM-centric interface matters when the study workflow must stay aligned to SWMM inputs and results review for repeat scenarios. PCSWMM centers its desktop workflow around creating, running, and reviewing EPA SWMM models with model editing built around SWMM inputs and hydraulics visualization. SEWERGEMS also supports GIS-driven network creation and provides outputs like flow, velocity, and surcharge for gravity sewer performance under different scenarios.
Hydraulic state reporting tailored to sewers and surcharge behavior
Surcharge and hydraulic state reporting is a key requirement for gravity sewer capacity and performance analysis. SEWERGEMS includes built-in support for surcharge and hydraulic state reporting across gravity networks. InfoWorks ICM complements this with section plots and profile views that help troubleshoot hydraulic behavior in coupled 1D-2D sewer and surface flooding models.
How to Choose the Right Hydraulic Simulation Software
Picking the right tool starts by matching the study physics and output needs to the tool's modeling workflow and coupling capabilities.
Match the modeling domain to the tool
Choose InfoWorks ICM when the project must couple 1D sewer networks with 2D surface flood behavior in one GIS-driven workflow. Choose TUFLOW or Flood Modeller when the project emphasis is coupled 1D-2D channel and floodplain hydraulics with spatial datasets and map-ready outputs.
Select the simulation type for the operational question
Choose EPANET for pressurized distribution hydraulics with headloss, pumps, valves, and time-varying extended period operations. Choose CivilStorm or SEWERGEMS when the question is gravity sewer or stormwater system behavior with steady and dynamic simulation, including pump stations, storage tanks, and surcharge-related hydraulic states.
Pick the workflow that matches model building and rerun discipline
Choose GMS for a GIS-to-mesh workflow that accelerates geometry cleanup, boundary assignment, and reruns inside a single project environment. Choose PCSWMM when teams must stay tightly aligned to EPA SWMM model structure and want a desktop-centered workflow for scenario runs and hydraulic results inspection.
Verify outputs for decision making before committing to a setup approach
Choose InfoWorks ICM or Flood Modeller when the output needs include visual mapping of inundation extents and depths plus troubleshooting views like section plots and profile views. Choose TUFLOW when outputs must include depth, velocity, water surface elevation, and time-series reporting across large domains.
Plan for compute and model complexity based on study size
For large study areas, prioritize tools that explicitly support efficient scenario management because InfoWorks ICM and TUFLOW can slow down without careful model design and workflow tuning. For simpler network-focused studies, choose EPANET or SEWERGEMS because their domain focus is narrower and visualization is centered on hydraulic states like pressures for EPANET and surcharge for SEWERGEMS.

Common Mistakes to Avoid
Several setup and workflow pitfalls show up across the covered tools, especially when model complexity is underestimated or when the chosen tool does not align with the study physics.
Choosing a coupled 1D-2D tool without planning for GIS complexity
InfoWorks ICM and TUFLOW can require specialist hydraulic modeling knowledge when deep parameter tuning is needed for customized GIS datasets. Flood Modeller can also require specialist hydraulic knowledge for complex model configuration, so model setup discipline must be planned before large-area builds.
Using a pressurized-network tool for gravity sewer or floodplain questions
EPANET is optimized for pressurized water distribution networks and focuses on pressures and extended period hydraulic behavior rather than sewer surcharge state reporting and 2D inundation. SEWERGEMS is built for gravity sewer networks with manhole-focused modeling and surcharge reporting, while InfoWorks ICM and TUFLOW provide coupled surface inundation options.
Running large coupled models without accounting for compute and storage limits
TUFLOW and Flood Modeller can demand significant compute and storage for large datasets and can slow runtimes without careful pre-processing and model design. InfoWorks ICM can also slow workflow for very large study areas without careful model design and scenario setup.
Expecting generic visualization to support engineering troubleshooting on complex hydraulics
EPANET visualization is basic compared with dedicated engineering suites and may require external analysis for deeper troubleshooting. InfoWorks ICM addresses troubleshooting using section plots and profile views, while Flood Modeller and TUFLOW focus on map-based outputs and detailed hydraulic fields like depth and water surface elevation.
